The Titleist AP1 was one of the very top rated clubs. Hitting the sweet spot was imperative which is why the average player did not choose this club, the better players liked the clubs. The Titelist reputation, while well deserved, may have influenced some of the golfers.

Building upon the high technology design and resounding success of the original AP irons, Titleist introduces the new high performance AP1 irons for avid golfers. The Titleist AP1 are multi-material, dual cavity irons that take the design mission of "Advanced Performance You Can Feel" to new heights.

The concept for the original Advanced Performance irons arose as a result of research that indicated serious golfers want performance with great feel, not performance at the expense of feel. The Titleist R&D team's advanced research group has been conducting extensive sound and vibration analysis aimed at reducing the harsh lower frequency vibration that causes poor feel in irons. This research led to combining several technologies and materials in the back cavity of the new AP irons resulting in a new Tuned Feel System to take feel to a new level.

The new Tuned Feel System is a co-molded medallion of soft elastomer and aluminum plate. This insert has been specifically designed to improve the sound and feel of each new iron. For the thinner face, larger cavity AP1 a hotter, more lively feel has been enhanced.
